– Press ON/OFF.
The instrument switches on in the normal Measure-
ment mode and will operate according to previously
set parameters. A SET PROBE routine should be car-
ried out before use (see section 5.5) The display will
show the conductivity of the material on which the
probe is placed or PROBE OFF METAL if the probe
is in air. The display also shows information such as
the operating frequency, measurement units, probe
code number, battery state and alarms (see below).
Also the word SET will appear on the bottom line if the
probe temperature has drifted +/–3 °C since the last
set routine was carried out. If the SET icon appears
then the set probe routine should be carried out to re-
store high accuracy measurement.
Example
Taking a reading of 60.5 % IACS (I) at a frequency of
500 kHz (H) with a probe whose code number is 5467.
At the bottom right a battery level of 50 % is indicated
and to its left the presence of the
icon indicates the
upper alarm level has been exceeded.
Normal measurement display:
